Autism Prevalence is Now 1 in 44, Signifying the Eighth Increase in Prevalence Rates Reported by the CDC Since 2000


The Autism Community in Action (TACA) shared the Center for Disease Control and Prevention (CDC) reports, autism prevalence has taken another jump in the wrong direction. A once rare disability in 1970 at 1 to 2 in every 10,000 U.S. children has continued to rise to 1 in 44 U.S. children.  Since 2000, this is the eighth increase in the autism prevalence rate as released by the CDC in their “Autism and Developmental Disabilities Monitoring Network” (ADDM) report.

“Since TACA started over 21 years ago, there have been ten autism prevalence numbers announced by the CDC. With each increase, I hope this number will provoke more people to care,” said Lisa Ackerman, Founder and Executive Director of TACA. “The CDC prevalence figure is based on similar methodology and represents a true increase. It is not because we are better at diagnosing autism. There is just more autism. This prevalence rate means even more parents are being told their child has autism. A prevalence rate of 1 in 44 can no longer be ignored. Families are counting on us to act and support them.  We cannot continue to overlook this epidemic.”

Autism is so prevalent today that almost every U.S. citizen has someone in their direct family who is affected by autism, they know someone with autism, or they know a family who is affected by autism.
